The Encyclopedia of Environment and Society brings together multiple issues, concepts, theories, examples, problems, and policies, with the goal of clearly explaining an emerging way of thinking about people and nature. With over 1,200 entries written by experts from diverse fields, the five volumes of this Encyclopedia represent more than a catalog of terms. Rather, they capture the spirit of the moment, a fascinating time when global warming and genetic engineering represent only two of the most obvious examples of socio-environmental issues.
